The effect of power supply ramp time on SRAM PUFs

Abstract: Physical unclonable functions (PUFs) are security primitives that exploit the device mismatches. PUFs are a promising solution for hardware cryptography and key storage. They are used in many security applications including identification, authentication and key generation. SRAM is one of the popular implementations of PUFs. SRAM PUFs offer the advantage, over other PUF constructions, of reusing resources (memories) that already exist in many designs. In this thesis, for the first time, it is demonstrated that… Show more

“…Ziyang et al, [23] have also used different power-up scenarios and analyzed the results for 256 bits of SRAM PUF. Elshafiey [24] also stated that the startup values of SRAM PUF are affected by the rising time of power supply. They implemented a 180nm Silicon-Germanium Bipolar/CMOS (BiCMOS) SRAM and confirmed the results.…”
